Crash was caused by incorrectly assuming, that rendered strip is meta when editing code in bulk, but this wasn't true and strip had no channels initialized, which caused crash on NULL dereference. Correct approach is to find list of channels where on same level as rendered strip, similar to how `SEQ_get_seqbase_by_seq` function works for list of strips.
